摘要:
The invention relates to a method for the production of polyisocyanate/polysilicic acid based resins with widely variable processability period and setting period by reacting one or more polyisocyanates with water glass optionally in the presence of one or more additives and/or auxiliary agents conventionally used in the production of polyisocyanate/polysilicic acid based resins. According to the invention the reaction is performed in the presence of one or more cocatalysts comprising mobile hydrogen of acidic character, wherein the cocatalyst is a compound comprising a structural unit of formula (I) a metal chelate thereof or a derivative thereof in which one of the mobile hydrogens of acidic character is replaced by a substituent X, wherein X represents halo, hydrocarbyl, hydrocarbyl-oxy, hydrocarbyl-carbonyl, hydrocarbyl-oxy-carbonyl or hydrocarbyl-carbonyl-amido group or a combined group formed from two or more of these groups, and the cocatalyst is used in an amount of at least 0.01% by weight calculated for the combined weight of polyisocyate(s) and water glass.

摘要:
A computer-based system and method are provided for assessing extrinsic and intrinsic work characteristics of people, and storing such data for evaluation of user pre-defined groups' Workstyles and using the Workstyles and additional survey data to develop design implications for the workspace in which such groups will work in an office environment. The Workstyles encompass multiple types of Workstyles which describe characteristics of where and how individual employees work, how much control they have over their work, and what kind of work they do. The design implications provide design guidance, which are expressed in relative terms and provide suggested guidance as to the development of the individual workspaces (workstations) for a group but do not dictate the specific design thereof.

摘要:
Methods, systems, and devices for rendering computer graphics using texture maps are disclosed. Multiple texture maps with disparate data types, such as a mix of integer data types for RGB colors and floating point data types for XYZ normal vector components, are passed as one texture map set to a graphics processing unit (GPU). Filter parameters and other interpolation parameters are re-used between the disparate texture maps. A user can specify a number of integer and floating point-based channels for processing at one time by the GPU, thereby customizing a texture set structure.
